Photohab is ideal for both professional and amateur photographers.

(tap the circles before they explode). Each game has 3 different levels, from easy to difficult.

Gpodder – is a libre web service that allows you to manage your podcast subscriptions and discover new content.

Tabula – If you’ve ever tried to do anything with data provided to you in PDFs, you know how painful this is — you can’t easily copy-and-paste rows of data out of PDF files. Tabula allows you to extract that data in CSV format, through a simple interface. And now you can download Tabula and run it on your own computer, like you would with OpenRefine.
